1. The problem statement, all variables and given/known data

A 2.00kg object attatched to a spring moves without friction and is driven by an external force given by

[tex]F= (3.00N)sin(2 \pi t) [/tex]

The force constant of the spring is 20N/m. Determine

a) period

b) amplitude of motion

2. Relevant equations

[tex]T= 2 \pi / \omega [/tex]

[tex]A= (F_o /m)/ \sqrt{ (\omega^2- \omega_o^2)^2 + (b \omega /m)^2} [/tex]

3. The attempt at a solution

a) [tex]T= 2 \pi / \omega [/tex]

[tex]T= 2 \pi/ 2 \pi = 1 s [/tex]

b) Um..[tex]A= (F_o /m)/ \sqrt{ (\omega^2- \omega_o^2)^2 + (b \omega /m)^2} [/tex]

however I'm not sure as to what the

[tex]F= (3.00N)sin(2 \pi t) [/tex]

[tex]F_o= 3.00N [/tex]

[tex] \omega = 2 \pi [/tex]

I'm not sure as to what that omega in the given equation is..is it [tex]\omega_o [/tex] or just the [tex] \omega [/tex] ?

b= 0 so that cancels out....

Thanks alot
